To all whom t may concern! y Be it known that I, OTTO FAHRNI, a citizen of the Swiss Confederation, and residing at Thoune, Switzerland, have invented certain new and useful Improvements in Machines for Perforating Jacquard-Cards for Emhroiclery-ldachines, ofv which the' lfollowing' is a specification.

This invention relates to machines for perforatingjacquard cards for embroidery machines of .the klnd wherein a, controlling device comprising amain determinative vmember havingmeans arranged Vin rows is provided for controlling the punching de;

vice for each component Yof mQv-ementbf the einbroidering frame, and wherein an auxiliary determinative member actuated by a lmember rotating' withthe said main determinative memberis provided forindicatingthe direction of movement ofthe same be-il yondA its Zerof position. f l

Machines 'f thisv kind known heretofore had the defect that wlienthe mainfdeter" 'minativie or control Vmember, lsuch as a cyl-V inder having perforations of ipins, Vmoved beyondl its initial position the operator had suddenlytoemploy more force in order to overcome the resistance opposing the operation of the pattern-copying apparatus, be

cause then the auxiliary determinative or control member, such as a segment or ykey.

had to be brought directly into a new. posi- Y. tion, the consequence ofy which always was that owiiigto the inertia of the moving masses at the usual working speed, the stitch to be made was always too large if one or both of its ends required an adjustment of the main controlmember to a its initial orizero position.` 4A primaryobject of this invention is to obviate vthis defect.V

the auxiliary control member by means of a positive clutch and positive backward transmission, means being provided for causing movementsof the sa-methat do not pass beyond the Zero position 4of themain control member to beiinoperative'on the" auxiliary control member for the pur ichiiigeoperation,y

and4 to return the auxiliary control member into the'zeio'position after thel saine.

To these and other ends, the invention position near,

their yone end by a cross frame 3 and carry at their other end a horizontal drivingshaft 4. A drivingpulley 5 is loosevonntheend" of this shaft that proj ectsbeyond the frame i. Thehub of.4 this 'wheel constitutes a crown'wheel having ratchet teeth Von its inner fend face, L which a similarly formed clutchmember 7 of an arresting disk 8 that is' axially `slidable alongl the shaft 1l: can be engaged'when the disk* 8 is shifted by the operator toward the pulley 5 against lthe action cfa lspring llsituatedbetween `these disksby'meanspof an anglellever 9 5 mi a ending ring io Connected therewith,

The pulley 5v can therebybe` clutched .with the shaftft so that'it willrotate the latter, in the ldirection of 'the arrowfshown inl Fig. l.

the springill the diskS is pushed away from and disengagedl from the 4pulley 5 whenever the roller 14 enters into the recess V13;A As

ioo'

soon as the roller 14 is at the bottom of this recess, the disk 8 is arrested and with it the shaft 4. Consequently, the claw clutch 6, 7 is disengaged once every revolution and always stops the shaft 4 in the same position. Y

Cams 15 and 16 and two cams 17 and 18 are fast on the shaft 4 between the two side frames 1 and ,2. The ,anti-friction roller 19 of a lever 20, 21, 22 coacts Vwith the periphery of the cam 15. rllhe downwardly projecting arms 21 and 22 are connected respectively to the one endvof two rods 23 and 24 of adjustable length, the other ends of 'which' are pivotally connected to angle Vlevers 25 and 26, respectively. Each of the same is provided at the free end of its upper arm witha tooth that slopes on both sides, by means of which a toothed wheel 27 arranged at the side frames 1, 2 above the angle levers 25v and 26 and havingtoothgaps or teeth corresponding with the shape of the saidtooth can be placed and arrested exactly in positions corresponding to pitch of the same. Y

The toothed wheels 27 are respectively fast on sleeves 29, whereof only one is shown, free to. rotate about the fixed spindle 31 common to the two. rlhe two wheels 27 have each onits innerend face a pinion 32, andr 33 respectively, of which the former meshes with a gear wheel 34 and the other with a gear wheel The wheel 34 is fast on a shaft 36, on which a sleeve 37 carrying the .wheel 35 is free to rotate; this sleeve 37 has outside the frame 2 a pinion 38, beside which is a pinion 39 fast on the shaft 36. j The pinions 38 and 39 are positively connected ywith a well-known adjusting apparatus, not shown, to be actuated according to a pattern drawing, whereof the pinion 3.8 for example brings about the adjustments for the horizontal feed, and the pinion 39 the. adjustments for the vertical feed of a frame of an embroidering machine. The pinion 38j imparts its rotation to the sleeve 37, and the wheel 35 to the one sleeve on the i spindle 31, whereas theipinion 39 acts by Vmeans of the`shaft,36, and the gear wheels 34 and32fon the other sleeve 29 on the spindle 31.

The sleeves 29 which, as will be understood from the above, are rotatable independentlyv`v one of the other, carry fast on them each a perforated cylinder 40, 41, herein referred to as main determinative members, between each of these and the allotted pinion 32 or 33 an arm 42 having laterally. projecting driving-,pins 43, further an'axially slidable worm 44 and 45 respectively driven by these latter pins, and lastly each a segment 46, and 47 respectively, herein, referred to as auxiliary determinative members, each rotatable between the two perforated cylinders 40 and 41.

Corresponding to the number of teeth of the wheels 27 the cylinders 40 are provided each with sixty axially disposed rows of perforations which, commencing with six as the largest number in the zero position, is each a different combination of holes. Of these sixty combinations each serves for determining a predetermined amount of movement of an embroidering-machine controlled by jaquard cards, the perforated cylinder in question being turned or moved a predetermined amount. For example, if a movement of one complete revolution of one ofthe perforated cylinders corresponds to a displacement of the frame (movement component) of 5 mm.A as a unit, a movement of the perforated cylinder from one row of holes to the next will correspond to a frame displacement of 1/12 mm., and a movement of two rollsto a frame displacementof 2/12 mm., and so on up to 60/12 mm. units.

When the perforated cylinders are situated in the zero position the rows of holes corresponding to 'zero are situated in the horizontal axial plane of thek cylinders opposite the reduced ends of six horizontal, axially slidable feeler pins 50 guided in two cross-bars 48 and 49. The other ends of the pins 50 are formed as fiat sinkers consti" tuting bolts which project close together between two lat bars 52 placed one above the other and provided with as many vertical holes 53 as there are sinkers extending between them. Into the holes 53 of the lower bar 52 there extend from below the upper ends of vertical punches 54,whereof the lower ends' extend through a fiat bar 55 into a bar 56 below the same and normally rest by means of a collar 57 on the bar 55. Between this bar 56 and a similar bar 60 below the same is a small gap 59 for guiding a card yband 58.

'lhese bars 56 and 60 are supported on a beam 62 that has a vertical longitudinal slot 61 and is suspenc ed at its ends from two vertical rods 63. These rods are guided to move longitudinally in a cross bea-m 64 that carries the bars 52 and 55, and are pivoted at their upper ends. each to the forked end of a lever 65. Betweenthese levers 65 the shaft 66 on which both arefulcrumed carries a lever 67, the free endof which coacts by means of an anti-friction roller 68 with the cam groove 69 of the disk 16, by which v at each revolution of the same a rapid vertical reciprocatory movement is imparted to "the levers 67,765, the rods 63, the crossbeam 62 and the bars 60 and 56. rlhe band 58 is thus also reciprocated vertically.

*lfY the path of the punches .54 is free, that is to say, if none -of the sinkers 51 covers one of the holes 53 of the lower bar 52, then allA the punches are lifted by the band, they cany move freely vertically and therefore make no holes in the bandi This is the case when someofthe feeler pins 50 can enter into holes in the cylinder 40 and 41 on their being moved toward'them in the manner described hereinafter. If there is no hole inthe cylinder opposite one or another of the pins 50, on 'the contrary, then Abetween two zero positions, that is within the same unit, for example between 1/12 and 59/12 units, no device is required for indicating the 'direction of rotation of the cylinders or the `direction of the stitch, since it follows at once from two adjacent combinations Vof perforations. Ifthe Zero position is passed in the one or-other direction, however, the card for eachperforatedk'cylinder must have a particular perforation 'which shall release in the embroidering pattern gear those members which -are responsible for maintaining the correct direction of movement of the embroide'ring frame beyond the limit of one unit, in order that when a cylinder has moved, for example, from 1/12 units in a negative sense to 58/12 units, the pattern gear shall not. feed the embroidering framein the positive. sense' from 1/12 units to' 58/12 units.v lFor this purpose the device that will now` be described is provided. i' i vEach of the cylinders 40 is provided on i its outer end with a spiral thread 71', whereof the beginning Vand end coincide with the zero position or Aperforation of theO cylinder and together form a step or shoulder A72. To these threads 71v is allotted. each a feeler pin 73 which differs from the feeler pins 50 in being of somewhat larger diameter; also in its retracted position it projects beyond the latter. In Figs.v 1 and 2 only one Y of these feeler pins 73 is visible. They are 'pivoted at their rear 'ends each to a twolarmed lever 74, from'which a link 75 leads to a bell-crank lever 76 that is fulcrumed on a vertical pivot and Vengages by means vof'a sliding segment 77 inian annular groove 78 formed in the hub of its allotted worm 44. The worm wheels 79 and 80, meshing Atherewith are each rotatably mounted on a lsleeve 81 which, in turn,.is mounted on an eccentric pivot formed on an aXial 83 adjustably secured in the cross-bar 3. The

'sleeve 81 carries at one'end a three-armed lever 84 (Figs. 1, 2V andp'3), and at its other end a lever 85 that isconnected by 'means ofa link86 and -two members 87 and 88 at right angles to one another with the forwardly (toward the left hand) projecting arm` k89 of itsallotted segment 46. A spring 90 bearing against the vlever 85v presses the whoseV upwardly projecting arm carries a pin in the form of a screw 91 having at its end facing the worm wheel a point with which it engages in recesses or notches pro-v vided that face of the wheel and thereby clutches theworm wheel,` with the lever 84,y

the arrangement being such that so far as the'aXial `playrof the allotted worm admits thereof, therworm wheelV drives thel pin, or vice versa, according as the worm or lever 84 is turned, while the clutch is' disengaged, however, by forcing the worm wheel axially against the action of the spring 90 when the lever 84 is turned further or indeed is turned Ain that direction'inv which the worm prevents rotation vof Y with it.

the worm wheel lin mesh v In consequenceofthis device,fhereinafter referred tofas acompensation device, when the perforated cylinders 40 and'41 are rotated thesegments 46 and 47 are likewise rotatedfbutv with a :considerably reduced velocity' owing to the reduction gearing, so that rfor each revolution of the perforated cylinders the segments are rotated only-a 'fraction of a revolution, but in the same direction, as is the case for example in counting mechanism, in whichy the counting member for the units `acts on the counting member for the tens. For marking the Zero position? each` of the segments 46 and 47 has `in the-middle of its arc three holes, into each of which a feeler pin 93' enters when the segments occupy'a central position. `The feeler pins 93 control'each a 4punch 54, Aanalogously to the pins 50, with the aid of bolt sinkers,'s'othat no holes are Vmade in the band when the alloted'feeler pins 93 can enter into holes in the segmentsf Consequently, it follows that holes are punched in the band when, Vas in the case of the pins coactingwiththe perforated cylinders, the feeler pins 93 strike against thefsegments.'

As this, inthe case of the perforated cylinders,v lconstitutes means for indicating the amount of displacement of the embroid'ering lframe, so `here this means can be used firstly for indicating the direction 4of motion of the embroidering frame for the stitch to be made beyond the unit of length and. secondly, for

indicating the amount of-such excess in the caseof each single stitch. e Y

For the lfirst ofthese indications, the segment 46 has in the middle of its breadth in its upper half, and likewise the segment 47 has-in the middle of itsbreadth, but inits lower half,\a vertical row of perforations (Fig' 3), so that the -middle 'feeler pin of the-segment 46 can not enter into av` 270 vworm wheel 79 or 80against the lever 84,L

hole in thesame when this segment moves upward. The reverse is the case `with the middle feeler pin of the segment y47, for it Acan enter into ak hole in the same only when the segment has `moved upward. From the combination of a hole in the pattern band due to a middle feeler of the segment 46 or `47 with a transverse row due to the allotted perforated cylinder there can consequently be ascertained the direction of the one component'of movement of the embroidering frame` beyond the unit length. How frequently this unit limit or initial position is exceeded in a sitich to be l5 made is seen from the combination of two other rows of holes of the same segment with a transverse row due tothe allotted perforated cylinder; for example, if the Zero position of a perforated cylinder is exceeded once the allotted segment moves out of the zero position one division of the cross rows whether the cylinder inA question make a complete or only part of a rev olution. lf Tit makes/one `complete revolution then the correct adjustment lof `the segment results vautomatically from the positive arrangement of the transmission; if it is only part of a revolution the described compensation device comes into operation, the allotted feeler pin 73 bearing on a more or less deep part of its spiral thread 71 corresponding to the amount of angular movement of the perw forated cylinder and therefore experiencing -3 5 a greater or less longitudinal displacement which is imparted by the lever mechanism 74, 75, 76 to the worm which, in turn, is thereby shifted. axially more or less and turns the worm wheel forward still further than it would be turned by one ycomplete revolution of the worm in question. This additional angular movement of the worm wheel is imparted by the parts 91, 84, 85, 87, 86, 88 and 89 to the vsegment '46 or 47 which is thereby so adjusted as if the allottedperforated cylinder had turned one complete revolution, in order that the feeier pins-93 shall actually register exactly with a hole of the segments when one is provided. This play of the compensation device just described above occurs also when the zero position of ar perforated cylinder that is shifted is not passed, only in this case the compensation device acts always in a negative, that is a backward sense on the 'segment, in order that in spite of the positive connection between perforated cylinder and segment, the latter shall always occupy the zero position when the feeler pins are moved forward. After each withdrawal of the feeler pins out of the perforated cylinders and segments, the segments whether shifted in one direction or the otherr are returned into the middle or zero position; this is done v65 by a lever 95, that carries a semioircular vby a linkv 108 with alever 109 coacting with Lec/9,80*?

yoke 94, acting `by means 4of this yoke from below on the downwardly slanting arm of t the lever 84 that is shifted out of its middle position until ythis lever lagain occupies the middle position, wherein both the laterally projecting arms of the lever 84 contact with the ends of the yoke 94 when the lever 95 occupies its upper end position. The two levers 95 mounted on a sleeve 100 free to rotate on a shaft 99 are actuated by the cam 17 75 tlrough the medium of lever-mechanism 96, 9 ,98. 1

`The feeler pins are'advanced toward the perforated cylinders and segments by springs 101 that surround the pins between the two 80 cross bars 48 and 49; these springs bear at one end against the cross bar 48 and at the other end against pins 102 that extend upwardly from the feeler pins and simultaneously serve for withdrawing the. feeler pins fromthe front into the rear end position with'theaid of a beam .103 that is disposed transversely over them and is vguided. in horizontal longitudinal slots vin the frames 1 and '2. The beam 103 is recipro- 90 cated by two levers 105 and 106 that engage vpivots 104 on its ends and are both fast on a shaft 107, vthelever 106,being connected the cam 18.

The @tra band 58 ts tta intermittently ty the pair of rollers 110, 111, i whereof the lower one, 110, has on its periphery two rows of sprockets 112 that take into holes punched in the band. For robtaining the requisite space between these holes the punches 54 for punchingthe same operate at onlyvevery second punching operation. vFor this purpose 4the path of the ltwo punches that are used is blocked by means of .bolt sinkers 117 at 105 every alternate movement of the roller 110 Ywhich is intermittently rotated by means of va ratchet wheel 113 fast on its axle, a pawl 114, `(Figs. 2 and 4) that engages with this wheel, a lever 115 pivotally connected with 110 the pawl and a cam 116 that is fast on the driving shaft 4and actuates this lever 115. rl`he sinkers 117 are pivoted to levers 118 Ymounted on a shaft 119 that carries outside the frame 2 a two-armed pawl 120 (Figs. 2 115 and 4.) This .pawl is pressed by a spring` 121 against the periphery of a notched disk 122 mounted on the ratchet wheel 113; the ratio of the number of notches in the disk 122 to the number of teeth of the ratchet 120 wheel 113 is 1:2, so that every" alternate movement of the"ratchet wheel the pawl 'bears on the top of a tooth of the notched follewing punchingoperation. The adjustment of the feed roller 110 into. the correctv position at any time, and its arrest in thesame, is automatically effected by means of a toothed wheel V123V that is mounted on the axle of the feed roller and has teeth slanting on both sides, between which engages a Spring-controlled pawl 124. Y

^ For making holes in the pattern band for the specialfunctions of an embroidering machine to be controlled by the same there are arranged besides the twoy feeler pins 73,

two sets of six feeler pins 125 which, like the pins 50, control each a punch by means of a bolt sinker and are controlled by a design plate127'that is common to a set of six and is'reciprocated vertically in vertical guides 126 by the voperator manually, or automatically by mechanismr not shown in the drawing.

y,The hereinafter described mode of operation of the described machine relates to only one of the perforated cylinders and its alloted lsegment and to one revolution of the driving shaft 4.

In the inoperative position of the machine the clutchA 6, 7 is disengaged, the'driving shaft 4 is arrested by the disks 8, 12 and the roller 14, all the feeler pins are in their rear end position, the'segments 46 and`47 are situated each in Vits zero position, each toothed wheel 27 is released by its pawl 25 o-r 26v and the perforated cylinders 40 are thereby also released so that they can be adjusted at will. e

The perforated cylinder 40, for example, is Set Ybyvturning the pinion 39. If'the adjustment has taken place, for example,rto 58/12 units fromthe zero position in a posi-` 40 tive direction, the perforated cylinder will not have made a` complete Vrevolution and the segment 46 will have been shifted downward from its ,middle position not quite one division between the holes, when the per- '45 foratedcylinder in Fig. 1 hasbeen ,moved A ftert the setting` of, the perfoclockwise. p p rated cylinder the arresting disks 8, 12 are shifted against the action ,of the` sprlngll by. actuating the lever 9V and the clutch 6, 7

50 is thereby engagedi` i v v. p

i When the shaft I4 is'rotated counter clockwise 'as seen in Fig. 1 the pawl 25 is first engaged .with the toothed wheel 27 and the perforatedV cylinder is therebyl so set and arrested that the desired ,row of holes is situated exactlyopposite the feeler pin`sr50, should this not be 'thel case already. The beam 103 is then :moved towardithe perfo? rated cylinder.l vAtthevsame time the feeler pins also shift forward, whereof the pin 73" first contacts with the spiral thread y71,

the feeler pins 125l for the holes of, thev special functions then or simultaneously' l contact with the design plate 127, and lastlyl the feeler pins or design pins 50 or respectively 93, contact with `the perforated cylinder 40 and the segment 46, respectively', the' segment having in the meantime beenl re-V turned by the compensation deviceinto the zero position, because the zero or yinitial position of the perforated cylinder was not passed when setting the same.

All `thefeeler pins 93 allotted to the seg# ment 46 enter each into 'a hole therein, and for' example the five lower'design pins 50 in 75 Fig. 2 enter into the perforatedfcylinder.- Consequently, only the` top design pin 50- enters into a hole:` of the perforated cylinder, While the five others butt against the' cylinder, block with their boltl sinkers 51`r 80- the path of the allotted'fpunches -which punch each a hole inthe card band 58 during its upward movement which now takes place. "f

Immediately after this punching operation lthe card bandis moved downward land* fed one step forward'and the feed roller 110 is arrested by the-pawl mechanism 123, 124. All the vfeeler pins moved somewhat' away from the perforated cylinderor segment are 90 thereupon withdrawn by means 'ofthe' crossv beam 103.

If the perforated 'cylinder during its previousadjustment had been moved beyond the initial orzero position Aand the segment 95 had'been setone' or more divisions away from its middle position, the replacement of thesegment would be included in the described sequence ofoperations, this being"ef fected by the yoke of the lever '95.7; Then 100 the feeler kpins are completely withdrawn and lastly-the arresting members -25 `and`27 ofthe perforated cylinder and the driving clutch of the shaft l4 are disengaged, and; the shaft 4 is secured againsty unintentional `105 rotation by the disks 8, 12`andthe roller 14.' `The perforated cylinder cannowj be set afresh, and the described cycle of operations can berepeated.
